One could not call themselves a Mathematician without first learning and mastering basic arithmetic. The same is true about Poetry; for a person to call themselves a Poet they must have an understanding of form. It is perfectly acceptable for a Poet to write with absence of form and structure, but it is not ok for a Poet to be completely ignorant of form. And for the record, writing Free Verse doesn’t make you a rebel, it makes you a conformist.
